The verified answer to “Books and Authors question: In a comparison beginning with The Adventures of Tom Sawyer, which of the following book–author pairs is incorrectly matched?” is The Adventures of Tom Sawyer — Nathaniel Hawthorne, option C. The source-backed, question-specific record explains: The Adventures of Tom Sawyer is correctly associated with Mark Twain. These three details—title, author, and language—form the decisive bibliographical combination required here. Mark Twain, a major American literary figure, is also associated with Adventures of Huckleberry Finn; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (The Scarlet Letter — Nathaniel Hawthorne; Things Fall Apart — Chinua Achebe; Train to Pakistan — Khushwant Singh) must therefore be tested as complete statements: one true fragment cannot make an entire option correct. A common examination trap is to confuse an author’s nationality with the language of composition, or a translation date with first publication. Revision takeaway: remember the compact chain “The Adventures of Tom Sawyer — Mark Twain — English — 1876,” and connect it with Adventures of Huckleberry Finn for stronger recall. This evidence establishes the bibliographic relationship required in this Books and Authors item. A correct solution must preserve the exact title, author, publication context, language, award or comparison requested by the stem. Similar periods, genres or national traditions do not make two book–author pairs interchangeable. Option C gives The Adventures of Tom Sawyer — Nathaniel Hawthorne and satisfies the wording of the question. The remaining choices—The Scarlet Letter — Nathaniel Hawthorne, Things Fall Apart — Chinua Achebe and Train to Pakistan — Khushwant Singh—do not satisfy the complete requirement.
